Jordan obtains a silver metallic unknown. Jordan measure the mass of the metal to be 62.307 g. When the metal is placed in a graduated cylinder that contains 22.3 mL of water, the new volume is measured to be 29.1 mL.
a) calculate the change in volume of water in the graduated cylinder.
b) calculate the density of the metal.
c) Jordan's teacher provides a list of possible unknowns. Determine the identity of the unknown.
METAL DENSITY (g/mL)
lead 11.35
tin 7.29
aluminum 2.70
nickel 8.90
zinc 7.13
d)If the identity of the known is correct, calculate the percent error for Jordan's density value.
e) Was Jordan accurate? Explain your reasoning
f) Was Jordan precise? Explain your reasoning

A student is determining the density of an unknown metal with a mass of 56.5 g. The student partially fills a graduated cylinder with water and measures the volume of the water by itself as 54.8 mL. The student then adds the metal to the water and measures the new volume as 87.3 mL. What is the density, in g/mL, of the metal?
